# Connecting iOS Devices

You can connect iOS devices to a Mac computer with a USB cable to run applications built for them from Qt Creator.

To be able to use Qt Creator on macOS, you must install Xcode, and therefore, you already have the tool chain for building applications for iOS. Qt Creator automatically detects the tool chain and creates the necessary kits to build applications for and run them on configured iOS devices.

You only need Qt libraries that are built for iOS. You can install them as part of Qt 5.2, or later.

## Configuring Devices

The connections between Qt Creator and an iOS device are protected by using a certificate that you receive from Apple when you enroll in the Apple Developer Program. The certificate is copied to the device when you configure the device.

The first time you connect the device to the Mac, you are asked to enable developer mode on the device. The next time you connect the device, Qt Creator detects it automatically. To disable automatic connections to a device that you do not use for development, select Preferences > iOS, and deselect the Ask about devices not in developer mode check box.

Note: The process of configuring devices and the UI varies slightly depending on the Xcode version that you use. We recommend that you use the latest available Xcode version.

To configure connections between Qt Creator and an iOS device:

1. Make sure that you have Xcode and Qt for iOS installed.
2. Connect the device to the Mac computer with a USB cable.
3. Start Xcode to configure the device.

   For example, in Xcode version 7.3.0, select Window > Device > + > Add Device to add the connected device.

4. To specify build settings:
   1. Open a project for an application you want to develop for the device.
   2. Select Projects > Build & Run to select the kit for building applications for and running them on iOS.

5. Select Run to specify run settings.

   Usually, you can use the default settings.

   When you run the project, Qt Creator uses Xcode to deploy the application to the device.

   Your signing certificate is used to sign application packages for deployment to the device.

Note: If you cannot deploy applications, because a provisioning profile is missing, check that provisioning profiles are listed in Xcode by selecting Xcode > Preferences > Accounts > View Details. For more information about how to acquire and install a provisioning profile, see Apple documentation.

## Viewing Device Connection Status

When you connect an iOS device to a Mac computer with USB, Qt Creator automatically detects the device if you have configured it by using Xcode. To view information about the connected device, select Preferences > Devices.

If the current device state is Connected, (the traffic light icon is orange), you need to configure the device using Xcode.

## Testing on iOS Simulator

If you do not have an iOS device or you do not want to create an account, you can test applications on iOS Simulator, which is installed as part of Xcode. Each Xcode version simulates a predefined set of hardware devices and software versions.

You can change the simulated hardware and software version in the run settings for the project. Select Projects > Run, and then select the device to simulate in the Device type field.

Qt Creator uses the Xcode version set as current on the Mac computer. To check the version, enter the following command:

`xcode-select --print-path`

To change the version, enter the following command:

`xcode-select --version`
